MAIN SOLAR THERMAL UNVENTED HOT WATER CYLINDER Energy efficient Unlike some other twin coil cylinders, our cylinders have a purpose designed solar heating coil at the base of the cylinder, ensuring maximum heat input and efficiency from the solar source. Easy installation Comes with all the benefits of the Main unvented cylinder plus a whole lot more. Designed specifically for solar applications to make sure it does the job perfectly. To make things simple, the Main solar cylinder is compatible with most solar thermal systems now available in the UK. The remote expansion vessel can be located in various places, to suit your installation requirements. PERFECT FOR YOUR CUSTOMERS: Provides low carbon domestic hot water Fast filling showers and baths Powerful hot water from your solar thermal water heating system Compatible with: Main Eco Elite System Low maintenance High grade stainless steel inner cylinder prolongs product life and ensures low maintenance. We re so confident of the quality of our unvented cylinder, we offer a one year parts and labour warranty, and will guarantee the stainless steel shell for a further 24 years. Main Heat *Savings vary depending on type of solar system used, location and usage patterns. See page 27 for more details. For specifications please see pages 18-19. 16

SPECIFICATIONS Siting the unit The Main solar cylinder must be installed vertically. Although location is not critical, the following points should be considered: The Main solar cylinder should be sited to ensure minimum dead leg distances, particularly to the point of most frequent use. Avoid siting where extreme cold temperatures will be experienced. All exposed pipework should be insulated. The discharge pipework from the safety valves must have minimum fall of 1:200 from the unit and terminate in a safe and visible position. Access to associated controls and immersion heaters must be available to provide for the servicing and maintenance of the system. Where these controls are installed against a wall a minimum distance of 250mm must be left. Ensure that the floor area for the Main solar cylinder is level and capable of permanently supporting the weight when full of water. Wherever possible the mains supply pipe should be 22mm. We suggest the minimum supply requirements should be 1.5 bar pressure and 20 litres per minute flow rate. The Main solar cylinder has an operating pressure of 3.5 bar which is controlled by the cold water combination valve assembly. The cold water combination valve assembly can be connected to a maximum mains pressure of 16 bar. Outlet/terminal fittings (taps, etc.) The Main solar cylinder can be used with most types of terminal fittings. All fittings, pipework and connections must have a rated pressure of at least 6 bar at 80 C. Operational summary Maximum mains pressure 16 bar. Operating pressure 3.5 bar. Expansion vessel charge pressure 3.5 bar. Expansion relief valve setting 6 bar. T&P relief valve setting 90 C/10 bar. Maximum primary circuit pressure. (Auxiliary coil, indirect only) 3 bar. Maximum primary circuit pressure 6 bar (Solar coil). Important note: THE MAIN SOLAR CYLINDER MUST BE INCORPORATED INTO A FULLY PUMPED SOLAR PRIMARY CIRCUIT. CONTROL OF THE SOLAR PRIMARY IS ACHIEVED BY THE USE OF EXTERNAL CONTROLS NOT SUPPLIED WITH THE UNIT. CONTROL MUST BE VIA A PURPOSE DESIGNED SOLAR HYDRAULIC STATION AND SOLAR DIFFERENTIAL TEMPERATURE CONTROLLER. Pipe fittings All pipe fittings are made via 22mm compression fittings directly to the unit. The fittings are threaded ¾ BSP male parallel should threaded pipe connections be required. Cold feed A 22mm cold water supply is recommended, however if a 15mm (½ ) supply exists which provides sufficient flow this may be used (although more flow noise may be experienced). A stopcock or servicing valve should be incorporated into the cold water supply to enable the Main solar cylinder and its associated controls to be isolated and serviced. Drain tap A suitable draining tap should be installed in the cold water supply to the Main solar cylinder unit between the expansion valve and the heater at as low a level as possible. It is recommended that the outlet point of the drain pipework be at least 1 metre below the level of the heater. Expansion vessel The expansion vessel is pre-charged at 3.5 bar and must be connected between the expansion valve and the Main solar cylinder. Secondary circulation The secondary return pipe should be in 15mm pipe and incorporate a check valve to prevent backflow. A suitable WRAS approved bronze circulation pump will be required. Outlet Hot water distribution pipework should be 22mm pipe with short runs of 15mm pipe to terminal fittings such as sinks and basins. Installation Connection to solar primary circuit The lower (solar) coil of the Main solar cylinder must be connected to a fully pumped solar primary circuit. The connections are suitable for 22mm copper pipe direct to the compression fittings provided. The connections are also threaded ¾ BSP male parallel should BSP be required. Plumbing connections Direct units require the following pipework connections. Cold water supply to and from inlet controls. Outlet to hot water draw off points. Discharge pipework from valve outlets to tundish. Connection to the auxiliary primary circuit (Auxiliary/ Indirect unit only). Primary connections are 22mm compression. However, ¾ BSP parallel threaded fittings can be fitted to the primary coil connections if required. Electrical supply Main solar units are fitted with 1x3kW immersion heater on indirect units and 2x3kW immersions on direct units as standard. The Main solar cylinder MUST be earthed. The circuit must be protected by a suitable fuse and double pole isolating switch with a contact separation of at least 3mm in both poles. 18
